the entomopathogenic-fungus-life cycle is associated with the synthesis and secretion of a number of toxic metabolites, including extracellular enzymes and the low-molecular weight compound (toxin). the potential for a successful pathogen relies on the ability to overcome the various host-defence systems. interaction between the fungus, tolypocla-dium (deuteromycetes), its secondary metabolite,...

Cellular manufacturing emerged as a production strategy capable of solving the problems of complexity and long manufacturing lead times in batch production. The fundamental problem in cellular manufacturing is the formation of product families and machine cells. This paper presents a new approach for obtaining simultaneous arrangement of part families and machine cells for cellular manufacturin...

In this paper, an analytical approach for the availability evaluation of cellular manufacturing systems is presented, where a manufacturing system is considered operational as long as its production capacity requirements are satisfied. The advantage of the approach is that constructing a system level Markov chain (a complex task) is not required. A manufacturing system is decomposed into two su...

The research in virtual cellular manufacturing (VCM) systems area gains momentum as markets have become more globalised. This is due to turbulent customer demands, characterised by frequent changes in product mix and volume. Therefore, if companies are interested in implementing manufacturing systems that can be quickly restructured with minimal cost and time, the approach of virtual cellular m...

In this paper, a generalized mathematical model formulation for cellular manufacturing system (CMS) using hierarchical production planning (HPP) approach is proposed. The model is applied to two different real case studies and is solved by using operation research optimization software (Lingo (12.0) program). The model is divided into three main steps as follows: data collection, mathematical m...

Contemporary cellular approaches to the development of manufactu ring architectures based upon lean manufacturing concepts are often hindered or prevented by the lack of a smooth regular demand for products. This is frequently the case in apparel manufacturing where demand is erratic because of the high variety of end items and the fickleness of fashion markets. Multi-Channel Manufacturing (MCM...

This paper presents a new mathematical model for integrated dynamic cellular manufacturing systems and production planning that minimizes machine purchasing, intra-cell material handling, cell reconfiguration and setup costs. The presented model forms the manufacturing cells and determines the quantity of machine and movements  during each period of time. This problem is NP-hard, so a meta-heur...
